Kelly Osbourne says jail is just the wake up call Lindsay Lohan needs.

Writing in her weekly Closer magazine column, Kelly, who was once friends with the troubled actress, said: "Lindsay Lohan’s been sentenced to 90 days in jail after failing to attend alcohol education classes that were part of a probation order. My heart breaks for her, because we used to be friends and I hate to see her in such a bad place."

She added: "The reality is, if you break the law you have to pay the price. I’m really hoping this will be the wake-up call she needs to sort her life out and get back to the old Lindsay we all love.

"She’s a really talented actress and I’d love to see her get her life back on track. I have to say though; writing “F*** You” on her fingernail for the court hearing was a really silly move."
